A new approach for calculating doubly coprime matrix fraction descriptions
Chun Fang · IEEE Transactions on Automatic Control · 1992
Using the concepts of state feedback in generalized state-space, explicit formulas for calculating doubly coprime matrix fraction descriptions (MFDs) of the transfer matrix of a regular state-space system and the polynomial generalized Bezout identity elements corresponding to those coprime MFDs are presented. They can be easily calculated with the help of existing computational algorithms and software packages.>
